CIGAR WRAPPING MECHANISM- Filed June 13, 1939 2 Sheets-Sheet 2 Patented Jan. 27, 1942 CIGAR WRAPPING MECHANISM Birger Hellstriim, Karlsudd, Vaxholm, Sweden, assignor to Aktiebolaget Formator, Stockholm, Sweden, a joint-stock company of Sweden I Application June 13, 1939, Serial No. 278,951 In Sweden June 14, 1938- 5 Claims.

This invention relates to improvements in cigar wrapping mechanisms.

In cigar wrapping mechanisms antifriction means have been provided whereby the flag of the wrapper is controlled after it has been released from the wrapper support and before it is completely wound about the head of -a cigar bunch, and it is an object of the present invention to still further improve said improvement.

In the drawings,

Fig. l is a perspective view, partly broken away, of a cigar Wrapper mechanism according to this invention, several parts being omitted in the interest of clarity;

Fig. 2 is an end view, partly broken away, of the mechanism of Fig. 1;

Fig. 3 is an enlarged longitudinal sectional view of an embodiment of the invention; and

Fig. 4 is an enlarged sectional view taken on the line IVIV of Fig. 3.

Referring to the drawings, the cigar bunch I is introduced between the revolving bunch rollers The cigar wrapper is conveyed to the cigar bunch by a suction carrier 8 which is movable crosswise over the bunch rollers and a wrapper tension plate 3 which is movable periodically towards the bunch rollers 1 into its foremost position as shown in Figs. 1 and 2. For the latter purpose a bell crank lever I2 is pivoted on a pin I3 in the frame M and actuated by a spring l8 so that its roller l5 rides upon a cam l6 which is secured to the revolving shaft H. A drum It! for conveying the wrapper flag 4 is associated with the tension plate 3. Thus the drum I is rotatably journalled on a sleeve 3|, which is introduced into an arm H which is pivoted at I9 to the tension plate. After the arm II has been swung upwards the drum Ill can be pulled off the sleeve 3| and be cleaned, or the sleeve 3| can be removed together with the drum I0 from the arm The drum ID has perforations 30 in its side wall. The sleeve 3| has an upper longitudinal slot 54 and a tubular extension 9 which is adapted to register periodically with an opening 13 of a suction chamber 32 which is secured to the frame I4. The slot 54 extends peripherally about 35 and it is positioned so that any perforation 30 of the revolving surface of the drum I0 is subjected to suction about before it reaches its uppermost position. At every time when the tension plate 3 is advanced into the position shown in Figs, 1 and 2 the extension 9 of the spindle 3| will register with the opening 13 of the suction chamber 32 so that suction is established within the sleeve 3|. Thereby only those perforations 3| of the drum H] which communicate with the slot 54, and consequently only the upper part of the drum ID, are subjected to suction effect.

In operation, the wrapper is moved by the Wrapper carrier 8 in the direction of the arrow, and shortly before it reaches the position shown in Fig. 2 the nicked flag 4 of the wrapper is transferred to the drum In which is rotated under the pulling action of the revolving bunch I and the wrapper 2 or under frictional action caused by the bottom surface of the wrapper carrier 8. By the suction action of the upper part of the drum ID the nicked wrapper flag 4 will be transferred safely from the wrapper carrier 8 to the drum I0 and even though the suction surface of the wrapper carrier 8 would be coated with paste. Thus any risk of splitting the nicked wrapper flag will be obviated. The

wrapper flag adheres to the sucking upper partof the drum In above the slot 54 but is released as soon as it leaves said upper part. When the wrapper flag has left the carrier drum Ill and been supplied to the bunch head the wrapper carrier 3 is retracted whereby communication between the sleeve 3| and the suction chamber 32 is interrupted.

I claim:

1. In a cigar wrapping mechanism, a wrapper delivery means, and air suction means operative to successively remove the wrapper flag from said wrapper delivery means and transfer said flag to the head of a bunch positioned in said wrapping mechanism.

2. In a cigar wrapping mechanism, a wrap per delivery means, a suction source, and a hollow perforated anti-friction carrier to be connected interiorly to said suction source to successively remove the wrapper flag from said wraper delivery means and transfer said flag to the head of a bunch positioned in said wrapping mechanism.

3. In a cigar wrapping mechanism, a wrapper delivery means, a suction source, and a rotatable hollow roller to .be connected with said suction source, said roller having a perforated cylindrical suction surface to successively remove the wrapper flag from said delivery-means and transfer said flag to the head of a bunch positioned in said wrapping mechanism.

4. In a cigar wrapping mechanism, a wrapper delivery means, a suction source, a rotatable hollow roller for connection with said suction source, said roller having a perforated cylindrical suction surface for successively removing the Wrapper flag from said delivery means and transferring said flag to the head of a bunch positioned in said wrapping mechanism, and a hol- 10w spindle, said hollow roller being mounted on and encompassing said spindle, said spindle being interiorly connected to said suction source and having a longitudinal slot for communicating suction to part of the suction surface of the roller mounted thereon.

5. In a cigar wrapping mechanism, a wrap er tension plate, a suction carrier movably mounted on said plate for conveying the wrapper flag to the head of a bunch positioned in said wrap- 5 ping mechanism,
